Dodgers pitcher Chad Billingsley underwent Tommy John surgery Wednesday evening and is expected to be out for about a year, the team announced Thursday.

The procedure -- an injured elbow ligament is replaced with a tendon taken from elsewhere in the body -- was performed by team doctor Neal ElAttrache in Los Angeles, and took about 90 minutes. Billingsley will begin physical therapy in the next seven to 10 days.

The right-hander had the option of undergoing elbow surgery last September but chose to rehabilitate the injury and received an injection of platelet-rich plasma at the time. He was on the disabled list because of elbow inflammation three times in the past year.

Since Billingsley is in the second year of his three-year, $35M deal, the Dodgers paid about $2.1M per win across 2012 and 2013 (Bills is a combined 11-9).

Since Bills pitched a total of 161.2 IP, that also equates to around $144K per inning.

Or, for every out recorded, Chad Billingsley earned roughly the equivalent of the median US household income (according to CNN).
